The present invention relates to the production of lower extremity supportive products including boots, shoes, sandals, leg braces, etc. In particular, the invention relates to systems and methods for providing a customized lower extremity product.
Participants in many activities utilize lower extremity supportive products to assist or improve their performance. In some activities, the products are also necessary for coupling the user in some manner to a required sports apparatus. For example, it is necessary for skiers to use some form of boots to couple their lower extremities to skis.
A skier's boot both provides support and encourages the skier to position their lower extremity in a particular position that is designed to maximize performance. Boots are generally optimized according to a single foot mold. Additional sized boots are generally created by enlarging or reducing the size of the original boot by a standardized amount. However, participants have a wide range of foot shapes, sizes, flexibilities, and performance abilities. Therefore, it is unlikely that a boot that has been sized up or down a specific amount from a standardized mold will match the unique characteristics of a particular participant's foot. This guaranteed mismatch results in a decrease in performance and the possibility of discomfort or pain.
Conventional lower extremity customization systems attempt to conform a lower extremity product that has been sized up or down a specific amount from a standardized mold. These systems include adding pads, applying force to pressure points, removing materials, etc. These after-market customization or “boot fitting” techniques are unreliable and may result in damaging the integrity of the boot. In addition, these techniques are generally done on site. Therefore, a boot fitter in one location may make radically different adjustments than a boot fitter at an independent location.
A second type of customization process involves the utilization of a liner or injection of a foam material that is conformed to a user's unique lower extremity characteristics. The process of conforming the liner or liner substance may include heating or injection while a user positions their lower extremity in the product. These systems may help accommodate a standardized lower extremity product to a specific participant's lower extremity dimensions, but they are limited. For example, a heat-treated liner is unlikely to relieve foot pressure for a person with severe foot eversion. In addition, these systems are ureliable and inconvenient. A heat-treated foam liner will deform to provide less support in the desired position over time. Likewise, an injected foam system must be reapplied after each time that a user removes the boots. In addition to the other limitations, these after-market systems still fail to provide the same level of performance to a participant that would be afforded if the participant's lower extremity matched the original mold used to create the product.
Other customization processes are designed to manufacture lower extremity products that specifically match the characteristics of the sole or bottom surface of an individual's foot. These processes involve either two-dimensionally tracing or three-dimensionally mapping the sole of the foot. However, the remainder of the lower extremity product is still made according to a standardized mold or according to a standardized format. Essentially these processes involve manufacturing customized footbeds or orthodics which are incorporated into a standardized lower extremity product such as a boot. The performance and comfort characteristics of a lower extremity product are not limited to the region in which the sole of a user's foot contacts the product. Therefore, these customization processes also fails to provide a level of customization necessary to maximize performance and accommodate the individual lower-extremity characteristics that affect comfort.
All of the existing customization systems fail to produce a truly customized product in a cost-efficient manner. Therefore, there is a need in the industry for a method of providing a customized lower extremity product that is truly customized to the unique three-dimensional characteristics of a customer's lower extremities for use in a particular activity.
The present invention relates to the production of lower extremity supportive products, including boot, shoes, sandals, leg braces, etc. One embodiment of the present invention relates to a method for providing a three-dimensionally customized lower extremity product. The method includes measuring and recording data related to a three-dimensional representation of a customer's lower extremities in an activity-specific optimal stance. The three-dimensional representation includes specific anatomical position information including extensions, flexions, rotations, inversions, eversions, etc. The three-dimensional representation also includes surface information including foot shape, ankle shape, sole shape, etc. The measurement and recordation is performed at a convenient location such as in close proximity to the customer's residence or at an airport terminal. The customized lower extremity product is then manufactured at an independent location. The manufactured customized lower extremity product is customized according to the data so as to support the customer's lower extremity in the activity-specific optimal stance. In addition, the customized lower extremity product may be delivered to a location that facilitates customer pickup.
In order that the manner in which the above-recited and other advantages and features of the invention are obtained, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

Initially, data related to a three-dimensional representation of a person in an activity-specific optimal stance, is measured and recorded, act 205. The activity-specific optimal stance is a unique total body position that maximizes a particular user's performance and/or minimizes their chance of injury while maintaining optimal comfort. For example, a generic activity-specific optimal stance would involve a particular amount of knee bend/articulation to improve balance and allow for quick reaction. However, an individual with severe knee injuries may be forced to assume a stance that has less knee articulation. As will be described in more detail with reference to
The customized lower extremity product is then manufactured according to the data at an independent location, act 210. The lower extremity product may be manufactured according to any well-known lower extremity product manufacturing process including but not limited to injection molding. The data is transferred from the location at which the act of measurement and recording 205 is performed to the manufacturing location. Well known data transfer techniques may be used to transfer the recorded data to a particular manufacturing facility. For example, the Internet, FTP, mail, or any other data transfer system may be utilized and remain consistent with the present invention. Because of the distributed architecture of this method, it is possible to select a manufacturing facility that can manufacture the product at a globally efficient price. For example, China is a preferred manufacturing location for many products because of its inexpensive labor. Alternatively, the product may be manufactured on-site if sufficient resources are available.
The customized lower extremity product is then transferred to facilitate customer pickup, act 215. After the act of manufacturing 210, the product may be shipped to a particular location that is convenient with customer pickup. For example, the customized product may be shipped to an affiliated retail outlet that is located in close proximity to the customer. Alternatively, the customized product could be shipped to a location to coincide with a particular customer's travel schedule. For example, if a customer is flying to a particular location, the customized product may be shipped to an airport to facilitate efficient pickup. The transfer of the product may include shipping and/or hand delivery. Additional acts may be included to allow a customer to specify a location that is convenient for pickup.

The data is then transferred to location #2 for manufacturing the customized product according to the data, act 320. The illustration shows a computer for receiving the data and some form of three-dimensional manufacturing device. Location #2 is generally independent of location #1 to allow for the most efficient manufacturing of the customized product. Many convention customization methods require that the customization be performed at the same location as where the measurements of the individual are performed. Location #2 may be a manufacturing facility which is equipped to receive data and directly implement the data into a manufacturing process that creates a product specifically tailored to the data. Various automated manufacturing processes may be utilized to effectuate an automatic process. Alternatively, a manual process may be used which incorporates the received data to manufacture the customized product. For example, the data may be used to create a plastic mold of an individual's lower extremity. A manufacturer may then use the mold to manually overlay materials to perfectly match the three-dimensional characteristics of the mold in the process of making the customized lower extremity product.
The customized lower extremity product is then transferred to location #3 to facilitate pickup, act 330. As illustrated, location #3 may be a retail outlet that is capable of receiving the customized product and delivering it to the correct customer. Various affilitate agreements may be incorporated so as to compensate the retail outlet a particular percentage of every sale. Additional acts may be incorporated to allow the customer to select the most efficient location for pickup. Alternatively, the customer's billing information could be used to automatically select the most convenient location for customer pickup based on proximity. Alternatively, location #3 may be the same as location #1 such that the customer is able to pickup their customized lower extremity product at the same location at which the measurement and recording of the data was performed.

However, the positioning of the customer in the activity-specific optimal stance must be performed in a manner and location that allows for the three-dimensional scanning of their lower extremities. For example, simply positioning an individual on a flat surface will allow for many of the outer surfaces to be scanned but will not allow for the bottom of the foot/sole to be properly scanned. It may be necessary to perform multiple scans to create the data that accurately represents the three-dimensional representation of the customer's lower extremity in the activity-specific optimal stance. The act of scanning 209, may incorporate various manual and/or automatic scanning techniques. For example, a three-dimensional scanner may need to be supplemented with at least one manual measurements of critical dimensions to ensure accurate data representation of the customer's lower extremity in the activity-specific optimal stance.
In an alternative embodiment, locations #1, #2, and #3 may be disposed in close proximity to one another and remain consistent with the teachings of the present invention. For example, the locations could all be arranged in a single building or facility. This system would provide customers with on-site and/or real-time delivery of their customized lower extremity product. However, this configuration is not as economically efficient as transferring the data to an independent manufacturing facility that is globally cost-efficient to allow for manufacturing and then transferring the manufactured product back to a location for efficient pick up by the customer.
Various combinations and/or modifications to the described embodiments may be utilized and remain consistent with the present invention.
